PHP封装的Twitter访问类实例

本文实例讲述了PHP封装的Twitter访问类。分享给大家供大家参考。具体如下：

    class Twitter {
     /**
      * Method to make twitter api call for the users timeline in XML
      *
      * @access private
      * @param $twitter_id, $num_of_tweets
      * @return $xml
      */
     private function api_call($twitter_id, $num_of_tweets) {
      $c = curl_init();
      curl_setopt($c, CURLOPT_URL, "http://twitter.com/statuses/user_timeline/$twitter_id.xml?count=$num_of_tweets");
      curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 3);
      curl_setopt($c, CURLOPT_TIMEOUT, 5);
      $response  = curl_exec($c);
      $response_info = curl_getinfo($c);
      curl_close($c);
      if (intval($response_info['http_code']) == 200) {
       $xml = new SimpleXMLElement($response);
       return $xml;
      } else {
       return false;
      }
     }
     /**
      * Method to add hyperlink html tags to any urls, twitter ids or hashtags in tweet
      *
      * @access private
      * @param $text
      * @return $text
      */
     private function process_links($text) {
      $text = utf8_decode($text);
      $text = preg_replace('@(https?://([-\w\.]+)+(d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $text);
      $text = preg_replace("#(^|[\n ])@([^ \"\t\n\r<]*)#ise", "'\\1<a href=\"http://www.twitter.com/\\2\" >@\\2</a>'", $text);
      $text = preg_replace("#(^|[\n ])\#([^ \"\t\n\r<]*)#ise", "'\\1<a href=\"http://hashtags.org/search?query=\\2\" >#\\2</a>'", $text);
      return $text;
     }
     /**
      * Main method to retrieve the tweets and return html for display
      *
      * @access public
      * @param $twitter_id, $num_of_tweets, $timezone

      */
     public function get_tweets($twitter_id, $num_of_tweets = 3, $timezone = "America/Denver") {
      $include_replies = false;
      date_default_timezone_set($timezone);
      // the html markup
      $cont_o  = "<div id=\"tweets\">\n";
      $tweet_o = "<div class=\"status\">\n";
      $tweet_c = "</div>\n\n";
      $detail_o = "<div class=\"details\">\n";
      $detail_c = "</div>\n\n";
      $cont_c  = "</div>\n";
      if ($twitter_xml = $this->api_call($twitter_id, $num_of_tweets)) {
       $result  = $cont_o;
       foreach ($twitter_xml->status as $key => $status) {
        if ($include_replies == true | substr_count($status->text, "@") == 0 | strpos($status->text, "@") != 0) {
         $tweet = $this->process_links($status->text);
         $result .= $tweet_o . $tweet . $tweet_c . $detail_o . date('D jS M y H:i', strtotime($status->created_at)) . $detail_c;
        }
       }
       $result  .= $cont_c;
      } else {
       $result  .= $cont_o . $tweet_o . "Twitter seems to be unavailable at the moment." . $tweet_c . $cont_c;
      }
      return $result;
     }
    }
